A long request to the dns server

[ofedotov51]

There is a problem with a long request to the dns server. It is shown in the example below. The request is sent from the pod and the problem manifests itself from the pod. I tried to solve the problem by doing forwarding, but it didn't help.

curl -w "dns_resolution: %{time_namelookup}, tcp_established: %{time_connect}, ssl_handshake_done: %{time_appconnect}, TTFB: %{time_starttransfer}, time_redirect: %{time_redirect}, time_total: %{time_total}s\n" -o /dev/null -s https://ya.ru
dns_resolution: 5.073743, tcp_established: 5.087487, ssl_handshake_done: 5.103775, TTFB: 5.166707, time_redirect: 0.000000, time_total: 5.193673s

I attach an example of forwarding.

servers:  
 - name:
   zones:
     - *.ru
     - *.com
   forwardPlugin:
     upstreams:
       - dns1
       - dns2:5353

cluster version 4.5.0-0.okd-2020-10-15-235428
